Feasibility Study of a Fully Implanted Long-term Glucose Sensor/Telemetry System in Diabetic Subjects

Abstract:

Achieving good blood glucose control in people with diabetes requires frequent blood glucose monitoring by a means that is widely acceptable to users. To this end, UCSD and GlySens, Inc., have collaborated on development of a fully implanted long-term glucose sensor/telemetry system. Reported here will be feasibility studies of the application of this system in a small group of people with T1D and T2D during repeated blood glucose clamps and spontaneous glucose excursions over a 6-month period. Also to be discussed is a glucose mass transfer model that predicts the dynamic sensor signals from venous blood glucose measurements, and allows assessment of the effects of local physiologic phenomena that affect the sensor signals, including glucose diffusion in the tissues, insulin-dependent glucose uptake by local tissues, the dynamics of the sensor itself, and measurement noise.
